We enter a fascinating church carved right into the rock: the Church of the Madonna di Idris. There are some surprising discoveries awaiting us.

Adriano is very happy with how things have been going for the new Olivetti portable typewriter, but his siblings and partners in the business are not so happy. For one thing, they don't like not seeing any of the profits.

Matera is all about caves and grottoes. There were many natural caves that were expanded to be used as dwellings and churches, and other man-made grottoes as well.

Teresa and Libero go to the movies together, and things seem great. But Libero has something important to tell her, something she had no idea about.

Alberto Angela us takes back in time, to a city that came about in a totally different way: splendid Matera in Basilicata. It's definitely worth a trip.

The "Lettera 22" portable typewriter is selling well, although Mauro isn't in complete agreement about the price. Libero and Teresa make some plans, and Mister Dalmasso comes around again.

We leave the Royal Palace of Caserta and head towards Cilento in Campania where there is a huge Benedictine monastery. When we see the term convento, we might assume it is a convent for nuns, but in Italian, un convento can be a religious community for either monks or nuns (or both).

Adriano shows Karen Bates around the new building and she writes her report. The new portable typewriter designed by Libero is finally ready.

Exploring the gardens further, we come upon a grotto, as well as what looks like an ancient Roman site, replete with original statues. It was all part of Vanvitelli's plan.

Teresa goes back to the factory, and finds out she has talent. Karen Bates, the American photographer, comes to visit Adriano, and he sees right away how he can involve her in one of his projects.

If we thought the interior of the Royal Palace of Caserta was amazing, we should get ready for even more amazement as we go outside and see the spectacular park — a true capolavoro (masterpiece) — which Luigi Vanvitelli, architect and engineer, designed, giving water the starring role.

Paola is more clearheaded after a night's sleep. Adriano isn't happy, but he has other things to think about such as the new plans for the compact typewriter. He and Libero get a visit from the girl-thief again.

The narrator makes us aware of the vast number of people necessary to run the Palace. We visit the most intimate place in the Palace: the queen's dressing room and bathroom. It is fascinating to learn all the ways in which it was outfitted to both pamper and protect the queen.

Paola is having trouble with Carlo and shows up at Adriano's in search of consolation.

Alberto Angela takes us from the public throne room to the private chambers of the Royal Palace. In order to obtain the desired wall coverings, a whole complex was built for manufacturing silk. It's still operating today. Incredibile!
